LEC to LES assignment

The algorithm according to which the LECS decides
which LES’s address to give a LEC. This is only used
if the registration type is set to distributed.

By Longest - The LECS supplies the LES address
that best matches the ATM address of the LEC.

By Equal (Round Robin) - The LEC is assigned to
the next distributed LES address in sequence
(each distributed LES is used in turn). This is also
known as Round Robin.

By Group - Each distributed LES on the ELAN is
assigned a group address. It is this address that is
returned to every LEC by the LECS. When this
option is selected, you must supply the Group
LES Address, a 20 byte unique address.
